Rumour: Some Guy Leaks Nintendo Wii U Specs, Some Other Guy Confirms Them

Another week, another batch of Wii U specifications – this time with an added bonus!

According to a bunch of gamers over on the forum (wait for it…) NeoGaf, the specification list of the Nintendo Wii U has been leaked. Nintendo’s new console will have a three-core CPU, 1.5GB Ram and an 8GB flash hard drive built in.

If these specifications seem odd or even familiar, it’s because similar specifications have been rumoured in the past. Still, the bonus here is that a second poster on NeoGaf claims to be able to confirm these specifications!

So, without further adieu, I give you the latest batch of rumoured Wii U specifications;

Main Application Processor

– PowerPC architecture.
– Three cores (fully coherent).
– 3MB aggregate L2 Cache size.
— core 0: 512 KB
— core 1: 2048 KB
— core 2: 512 KB
– Write gatherer per core.
– Locked (L1d) cache DMA per core.

Main Memory

Up to 3GB of main memory (CAT-DEVs only). Note: retail machine will have half devkit memory
Please note that the quantity of memory available from the Cafe SDK and Operating System may vary.

Graphics and Video

– Modern unified shader architecture.
– 32MB high-bandwidth eDRAM, supports 720p 4x MSAA or 1080p rendering in a single pass.
– HDMI and component video outputs.


– Unified shader architecture executes vertex, geometry, and pixel shaders
– Multi-sample anti-aliasing (2, 4, or 8 samples per pixel)
– Read from multi-sample surfaces in the shader
– 128-bit floating point HDR texture filtering
– High resolution texture support (up to 8192 x 8192)
– Indexed cube map arrays
– 8 render targets
– Independent blend modes per render target
– Pixel coverage sample masking
– Hierarchical Z/stencil buffer
– Early Z test and Fast Z Clear
– Lossless Z & stencil compression
– 2x/4x/8x/16x high quality adaptive anisotropic filtering modes
– sRGB filtering (gamma/degamma)
– Tessellation unit
– Stream out support
– Compute shader support
– GX2 is a 3D graphics API for the Nintendo Wii U system (also known as Cafe). The API is designed to be as efficient as GX(1) from the Nintendo GameCube and Wii systems. Current features are modeled after OpenGL and the AMD r7xx series of graphics processors. Wii U’s graphics processor is referred to as GPU7.

Sound and Audio

– Dedicated 120MHz audio DSP.
– Support for 6 channel discrete uncompressed audio (via HDMI).
– 2 channel audio for the Cafe DRC controller.
– Monaural audio for the Cafe Remote controller.


– 802.11 b/g/n Wifi.


– 2 x USB 2.0 host controllers x 2 ports each.
– SDCard Slot.

Built-in Storage

– 512MB SLC NAND for System.
– 8GB MLC NAND for Applications.

Host PC Bridge

– Dedicated Cafe-to-host PC bridge hardware.
– Allows File System emulation by host PC.
– Provides interface for debugger and logging to host PC.

Fact or Fiction?

First of all, there are a lot of website saying that these specifications have been “confirmed” and are “real”. This is not the case, because Nintendo have not confirmed them. No real developer or publisher have confirmed them. The only person who seems to have “confirmed” them is a guy going by the name of lherre on NeoGaf.

That’s hardly rock solid evidence.

But I’ll admit, there’s sufficient tech-speak in that list to keep most people wondering “why make it up?”. But this is the internet.

But let’s humour them for a moment; what do these specifications mean for the Wii U?

Well, firstly – it’s wicked powerful. It has three times the amount of RAM as the Xbox 360, for instance. The Wii U probably wont have much to worry about with the next batch of competitor’s consoles, if these specs are true.

But some of the specifications sound a little too good to be true. Such as the “High resolution texture support (up to 8192 x 8192)”. This is a huge amount of resolution. There’s a crude, fan-made modification of Skyrim on YouTube that claims to use this resolution for textures and the results are phenomenal.

It’s an awesome thought that Wii U will handle these types of graphics, but it might just be wishful thinking at this point. That doesn’t make it a smoking gun, though. It would, however, bring into question some media reports that the Wii U is “only as powerful as the Xbox 360″.

So our advice is treat this is a rumour, because Nintendo have not yet confirmed a damned thing.

    Hopefully Nintendo will just give us the specs very soon and kill all the rumours that keep starting up and spreading around :D

    Nintendo pretty much never discuss full specs but if there is any truth to the RAM figure then I think the wii u will silence a lot of critics. Square Enix recently stated (referring to their next gen demo at e3) that RAM will be the biggest challenge facing the next gen consoles. 4 times the RAM of the 360 then? Yes please!

      Mmm… It’s true that Nintendo never really come out and say “these are the specs” – they did with GameCube, and it was the most powerful on paper, but ‘everyone’ sees that console as a failure… Then with Wii, they held back the specs, it was the least powerful, but has still managed to sell more consoles than PS3 and Xbox 360 combined..

      So, I can see why Nintendo think the specs don’t matter: they don’t.


      • Richard Roberts

        That’s a good point with the GameCube. It was criminally overlooked. Ironic really as its sales we’re harmed by lack of DVD playback now MS and Sony face criticism for concentrating too much on media features of their systems rather than games recently. Times and attitudes it seems, have changed.

        The XBOX1 blew away the Gamecube out of the water with it’s 733MHZ CPU vs 485 MHZ CPU on Gamecube. XBOX had vertex Shader and faster GPU while Gamecube did not. Xbox had dual 200 MHZ Audio DSP’s while Gamecube only had a single 81MHZ Audio DSP which was reused dor Wii and rehashed a 3rd time for the Wii U only upclocked to 120MHZ.which is STILL inferior to the XBOX 1 meaning some of Wii U’s 5.1 surround sound is still gonna have to done on the Main tri-core cause of it’s weak outadated Gamecube/Wii audio DSP the Wii U inherited just for the sake of backwards compatibility.

    I think this one is sort of true (this one guy who I know to be right most of the time, said that, that one guy who confirmed it, is right most of the time). And the best part is (if this rumor is true): these specs are from a Wii U development kit from late last year! That means that the development kits are now most likely more powerful, in fact some people think that late last year it was running a custom AMD Radeon 4850, but now it’s using a custom AMD Radeon E6760, which is better in meany ways.

    And this some guy doesn’t give a damn about specs. As long as it plays games i want it to, This guy is going to be happy.
